Brighton striker Evan Ferguson became the fourth player to score a Premier League hat-trick at 18 years or younger.
Ferguson scored a hat-trick in victory over Newcastle.
Chris Bart-Williams, Robbie Fowler, and Michael Owen (4 times) have the other players to achieve the mark.
Ferguson said: "It is fresh so it is hard to take in as a kid you want to score as many goals in the Premier League, so when you score a hat-trick it is a good day."
